Tables with skycoords

[keflavich]

Describe the bug
When I try to open a FITS table that contains a skycoord column, I get the following error:

Traceback (most recent call last):

It's not just FITS tables, ecsv's too.

@astrofrog Any idea of a workaround or solution for this? I'm pretty well blocked from using glue for any application I'm interested in while this is in my way.

@keflavich - sorry for not getting back to you sooner! This is likely an issue with mixin columns in general. This is an issue with glue-core, so will move the issue there.
